Intel(R) Atom(TM) CPU E3845 @ 1.91GHz, Linux 4.18.7-rt5 (Profile)

Latency plot of system in rack #b, slot #6
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system
The worst-case latency is about 1.09 times higher under extreme CPU load.
Results of all systems under extreme CPU load are combined on this summary graph.
The worst-case latency is about 25.92 times higher under graphics load.
Results of all systems with accelerated graphics are combined on this summary graph.
Characteristics of the highest latencies:
